A The primary object of the presentinven- 3'5 tionis topi-avide a wheel having a convenieiitly assembled in'closed spi'ingiorganization or sections carrying springs capable of de taclmieiit without removing all of said' sec: tions when it is necessary to repair or replace 2f) the springs-attached to any one of the individual sections andto so seat or apply the "sections-carrying the springs that-shifting movement and -wear on the `fastening devices Afortlie sections'will be prevented. The A2i springs are also inclosed to protect the same,

' and eoi'ipeiating therewith is an outer elastic shoe or eleiiclier which serves as a protective means. l

. With these and other objects andadvans3 tages'in vien", the invention consists in the construction 'and arrangement; of the several pai-ts which will he more fullyhereinafter.

specified and constituting an improvement on the construction illustrated in my Patent Number 925,930, datedfJnneQQ, 1909.

In the drawing: Figui-e1 is a side eleva- 'tion of a wheel` partially broken away and shown in section, and embodying the features of' the i'nveiitioin Fig. 2 is a trans- 4-3 verse vertical seetin through the wheel felly and tire portion. Figa 3 is a detail perspective view of a portion of the outer band of the tire showingr one of the spring carrying sections and the manner of forming contining seats in said band to receive the sections. Fig. 4 is a View lsimilar to Fig. 3 of the outer tire band showing a modification in the 'construction of the confining seats for the spring carrying Sections.

The numeral l designates 'a hub' having spokesQ radially projecting therefrom andoonnected to s telly 3, to which side plates l l are removably ap'lied and have outer inturned or bent edg s 5 to form seats or means for securingtlie outer shoe lor clencher' 1n applied position.

The vffheetstruoture, so fai' as the hub, spokes and felly are concerned, is not essential and any piet'erredjorsuitablevf'oi'in of wheel may be adopted andfhave the ,features ot' theinvention applied thereto. Likewise the side' )lates l may be modified in contour andmo e ot' application, and the features.

ot the invention will'now be particularly 'de. scribed. v

Surrounding theA f'elly 3 at. a suitable dis*- tance from the latter and in' concentric lrela-1 i tnnous and has formed therein at regular intervals a plurality of confining seats 7,

tion thereto is a metal band (wliiolit is con-, V

ivliicli'a're 'constructed by suitable `means.

Within. the seat .7, spring' carryingjan'd -attaching seotinsS are fittedand secured, said sections consisting of stripsA o f metal -longitudinally cnrvedfto' conform Atothe contour of the band to which they are iplied and of thinner materialltlian.the-band. As shown in the present-finstancc, t'wo springs 9- are ,held by each section 8, the said springs 9 having theironter terminals secured lto the section.A Eachsection `is removably attached to the band, reierably'by nutted fastenings' 10,' liavingt e nutted extremities projected inwardly or. the mits -11 applied against the inner side of each section so 'as to render the same accessible when it. is desired to .remove any one of the sections and without dissociating or disturbing the remaining parts and Aparticularly the `outer portion of the tire, lWhich-will be presently specified. j

The spring carrying or supporting sections 8 are provicledwith headed studs'12 to which the outer ends of the springs 9 are secured, and the inner endof each spring is held4 in close contact with the outer 'edge of the felly and engaged by the head of a. bolt 1% extending' through the felly and engaged by 4a separable nut and washer 14 exposed at the inner periphery of the felly and whereby the several springs may be released frein the telly and each section with a group of springs-detached from the band 6 and withdrawn for repair purposes or for replacement by a similar section and springs without rcmovingir the remaining springs or requiring a 'complete disorganization of the tire structure'.

The side plates 4 are Secured in place by removable fastenings and either one or both' may lie separated from the felly 3 to .expose the rim' sections just explained.

A simple modification in the coi'istructiou-v Astrain on the astenings for said seetionsi of ille :md ce1 in. strilin'r u 3 end .and side inf-s l5 and 16 to receive. the section. 8 between them. Both forms 'o'- seats, as particularly shown by Figsjf and 4, prevent dis lacei'nent .of the sections either longitudine ly or laterally 'with reletiento 'the bend G. Itis obvious that the wheel, 'when running, would have' a tendency to throw the sections' S out .of place if loosely appliedegainst, the said band and to impose considerable wearinor no counter-acting means is provided. The forms of seats in the hand positively retain the sections in applied position and prevent any tendency to movement'- of the seid sec- -tions and also relieve the fastenings 11,01?

Wearing' strain or liability of shearing -or breakge. Over the Aband an outertire or clencher 17 .of'usual vform is appliedand snugly. embraces ,the bandl 6 carryingI the sections, and has the side ges thereof 'removably secured in tlie bentedges 5 of the side plates 4, as clearly shown by Fig. 2. In this improved construction the outer tire or clencher 17 direct-ly hears on the band Gfand the spring carrying sections endsprings, together with the band, `rre fully inclo'sed by the lates 4 'nd the said Aonteitire or clene ier, and dust and dirt ere thereby excluded from the springs or the smashetween theouter edge or face of the telly and the secured edges of the outer tirev and 'consequently meticnl ,service of .the springs will 'ne pro onged. 1

By the use of the tire organization just explained, the inconvenienceslend disadvantages erising'from the punctnres of diferent' portions df pneumatic tires asj'cornmonly emdining seats 7 is shown by et, l ployed are avoided, es a puncture or e cutJ4 5 in the outer tire or rleneher 17 will not .im-

pair lthe usefulness oi the'tire embodying the features ot the invention, liurtherrnore, the improved tire will withstand greater strain,

-due to slridding or in making sudden turns',

than the ordinary form of tire now used.

c'lhe construction hereinhefore described essentially differs fi'om'that'diselosed in my Patent No. 925,930, dated June 22, 1909, in the-use of confining seats for the sections carrying the springs, there being no confim' ing seats disclosed in' the said patent.

What is claimed is:

1n a wheel, the combination of a telly, .a

band surrounding and spaced from the felly, av plurality of sections dis osed against the inner side of the band an carrying a plurality of sprin rsv projectinginwardly to the felly, the ban having means on its inner side for reventing movement of the. sec tions botllij transversely and longitudinally of the band, 'fasteningmeans for removably securing the sectionsto the band and protected as to weer by the means. -for preventing,r movement ofthe sections transversely and longitudinally of the band, nndi'fisten ing devices for securing the terminals of the springs to the iscetionsend for removably holding the springs in connectionwithhthe felly. v v A l ,In testimony whereof I have hereunto set.
